various sums for wa es or the like and has for its object. to sii'npiify the construction of such machines and render the machine less liable to get out of order.

According to this invention the machine (omprlses a series of keys a series of bell crank levers each operated by the depression of a key, a series of selective strlps one or more of which is positioned by the move-- ment-of a bell crank lever on the depression of a. key the positioning of the selective strips causing one or more of a series of pins to be moved along a rock shaft. These pins are so mounted 011 the rock shaft that while they can be moved along it they must rotate with it rotation being imparted to the rock shaft on the depression of each key. A series of ejector rods are so disposed that they an each be engaged and operated by one of the pins on the rock shaft when this pin has been moved along the rock shaft by the positioning ofthe selective strips. The end of each e ector rod can enter into one of a series of coin troughs and eject one -or more coins therefrom the coins conveniently falling thence into a chute or suitable receptacle. There is preferably combined with each ejector rod :1 device whereby the end of the rod is caused to drop after a coin has been ejected so that the end of the rod is relieved from the weight of the pile of coins during its return movement this return movement being effected cithcr positively by the operation of the rock shaft. or by spring action.

The coin troughs arc conveniently all so mounted thatthcy can rcmovc together from the machine thus enabling the contents to be easily transferred either from one machine to anothcr or to a. safe this arrangcmcnt also facilitating refilling the coin troughs.

The machine can he used with any known system of coinage but in the accompanying drawings is illustrated and dcscrihcd as being constructed for use with the English coinage. The adaptat on of the machine for use with coinage onthe decimal or other Specification of Letters Patent.

Like letters indicate like parts throughout the drawings.

The apparatus described hereund is closed in by a casing which prevents unan thorized access being bad to the contents of the coin troughs and excludes dust but in the present description and illustrations this casing is omitted for the sake of elearness. This casing may obviously vary in its construction and arrangementaccording to requirements. The machine has a main frame comprising end plates A connected by a lonitndinal member A which carries the seliietive strips and by a second longitudinal member A which is of channel Section and.

carries the key actuated levers. There further a front plate B the ends of which are rigidly secured to the end plates A. This front plate ll is curved and carries the coin troughs ll each of which is partially inclosed so as to retain the coins in position and allow them to be ted by gravityto the points whence they are ejected. The upper end ll oi each coin trough is open to allow of the ready insertion of coins. The lower most coin in each trough rests on a plate or annular llange I3 above which is an opening B" of such dimensions that the coin can be ejected theietln'ough whence it falls into a hopper C being delivered through an opening G into the hand or any receptacle which may be placed thereunder. At the back of each coin trough opposite the point where the lowermost coin will lie is an opening B in which lies the end D of an ejector rod. D. Each of these rods is free to be moved longitudinally passing through a carrying plate A which runs between the end plates A. The rear end of each ejector rod D curred round as at D to form a slot I)" which is transverse o the path of motion of the ejector rod.

Above the hooked rear ends of the ejrctcr rods is disposed a bar E which rocks in bearings E formed in the end plates A. I (In this bar E are mounted a series of collars E each carrying a pin the end of which can engage the slot D in the rear end of a (ZOX'l't'fSLlUllCllllg ejector rod D. The bar 1) of square or similar cross section or provided with a feather so that. the collars E with their pins PI must partake of the rotary motion imparted to the bar E in the manner hereafter described, the collars I" however being a sufficiently loose fit on the bar 1) to allow of these collars being moved longitudinally along the bar F. By this longitudinal movement the pins E are caused to engage with the slots D of the ejector bars or kept clear of these slots and it will be seen therefore that since on the depression of each key rocking motion is imparted to the bar E in the manner to be herelnafter more particularly detailed the pins E by their oscillatory motion will tend to impart longitudinal moven'lcnt to the ejector rods 1). Such nioven'ient will not however actually be imparted to the rod 1) unless the collar E of the pins E corresponding to this ejector rod has been moved along the bar E so as to bring the pin E into engagement with the slot l)". The rod thus engaged will therefore more I'm-ward and return with the rocking motion of the bar E. It is to be noted that the extremity of the hooked por tion I) of each rod l) lies at the back of its corresponding pin E hen the lattcrand its collar E is in a position such that the pin E is iz'ioperativc to move the rod D in the forward direction. The pin E is however able to operate on the end D of the rod 1) to more the latter inward and to return it to ll normal position of rest should this rod l) have received accidentally or otherwise an out ward movement. Thus the mechanism :uniomatieally insures the retention of the ejector rods in their positions of rest without the aid ol springs or weights for each individual ejector rod. The disposition oil the l'iooked end I) also makes certain that .EH'll ejector rod is returned to its normal position even it the collar I) and pin I should be in process of returning to their normal inoperative positions wherein the pin E is out of engagement with the slot D This allows o'l rapid operation of the machine. Above the rocking bar E lie the selective strips l in number corresponding to the number olwollars and pins on the rocking bar l this number of course coinciding with the number ot ejector rods and coin troughs.

Each selective st rip is conveniently formed of a flat piece of metal so that all the strips will lie side by side in the i'nanncr clearly illustrated in Iiigs. 1- and 5 and thus occupy a very small space laterally. Certain of hese strips are shorter than others. The ends 01' the onger strips project through openings in each end plate A of the machine being carried at an intei mediate point by a bracket A on the longitudinal member A. The shorter selective strips hare ne end projecting through the lelt'hand end p A and are supported by that plate and the bracket A". Projecting laterallyirom the under edge of each strip F are two arms F which lie on either side of one of the collars 3 On the upper edge of each strip F one or more projections F are formed. The number and disposition of these projections is such as to insure the selection of the nor-- essary strip or combination of strips required to etlect the delivery of the coins necessary to make up the total sun'i'which is to be deliverei'l at each manipulation of the machine.

Over the selective strips are carried in the channel frame A previously referred to a. series of hell crank levers Which connnuni cate the motion of the keys to the selective strips and effect the selection of the neces sary combinations of the latter.' Each of these bell crank levers comprises an arm Gr' having a rounded nose G and-adjac thereto a flat G". The second arm G is of shape and width corresponding to the number of selective strips F whose projections l this arm G is to engage. The arms (5: and G are formed on a body portion (i which is mounted on a spindle G whose ends lie in beatin s formed in the channel member A Each key H is disposed on the upper end of a key rod H whose lower end is cut into the key a nose H adapted to bear upon the Hat (3 of the arm G of a bell crank lever. The

lower end of each key rod l-l passes through v a corresponding openin in the channel member A which thus i orius a guide for rod the upper portion of the key rod being {guided in aplate A which closes in the to of the apparatus around and helow the eys. A coiled spring H is disposed around each key rod H the lower end of this spring bearing on the member A while the upper end is either attached to the rod H or bears against a collar formed thereon. These springs II" serve to return the keys to their normal position after they have been depressed.

Each key rod is provided with a lateral projection H which lies over a rod J which runs throughout the len 11 of the machine between the two rows of ey rods. The ends of the rod J are carried on a quadrant K pivoted at K'on the frame plates A. The periphery of this quadrant is toothed and engages with a pinion L mounted on a stud L on the side plate A. A lever arm L is carried by this pinion and rotates therewith having pivoted to its end at L a link M whose other end is pivotally connected to the end of a. lever arm E mounted on the also return to their in lial positions carryrocking bar E. A second lever arm E is also. mounted on the rocking bar and has connected to its end a coiled spring N whose other end is secured at N to the frame plate A. There is a quadrant K pinion L with links M and lover arms E E with spring N at each end of the apparatus.

The operation of the mechanism above described is as followsaJVhen a key H is de pressed during the initial downward movement of the key rod H the end H of this key rod bears against the flat G 01 the arm G of its bell crank lever and inovesthis lever about its spindle G". This movement causes longitudinal inovementof the selective strip or strips F with whose projection or projections the arm (i of the bell crank lever engages- This results in the lateral, movement of one or more of the collars E with their pins E on the rocking bar E thr; moving a pin E into engagei'i'ient with 1 slot I)" of an ejector I). At the moment when the hell crank lever (l G has moved to an extent sufficient. to insure the required positioning of lhe selected collaror collars I? and pin or pins l'l" the bell crank lever (1: G is in the position shown in dotted lines in Ft 5. it will then be seen that the continue downward movement of the key rod causes the end H" of this rod to slide off the flat G and over the rounded nose G of the lever arm G so that. further downwardmovement of the key rod is possible though further movement of the hell crank lever cannot. and does not take place, this lever being also locked aga inst return itiovcinent by the nose of this lever bearing against the side of the key rod II as shown in dotted lines in Fig. 8. At the stage in its downward movement when the key rod ceases to operate on the hell crank lever the lateral projection ll on the key rod hears upon the rod J and the continued downward llll) "illl'l|l ol' the kev rod causes the rod J to be depressed and consequently the quadrant l\' to he moved abd'ut its )ivot K. This results in rotation of the pinion ll wl'ierrby through the link M and lever arm E rocking motion is imparted to the bar I) together with the pins F," carrie l thereon. As a result of this each pin I which may have been positioned lo engage with a slot I) of an ejector rod I) imparts lon itudinal movement to thn't ejector rod wit i the result that a coin in the [rough controlled by this ejector rod is thrown out into the hopper C. On releasing the key which has been depressed the parts-are returned to their normal positions the rocking bar E be ing returned by the spring N the pins IQ simultaneously drawing back the ejector rod or rods D which have been operated. The quadrant simultaneously is thrown back into its position of rest the key rising under the influence of the spring ll. The selective strip or strips F whirh have been moved ing with them the he crank lever (i G" which W15; operated by the depression of the key. The return inf these selective strips l is automatically effected by the nuj-ehaiiisin shown more particularly in Fig. 18.

In each selective strip there is formed av notch I all the llfltCllK-h F being so positioned that when in line all the selective strips are in their normal positions ready for setting. Engaging with the notches F is a broadened end 0 of one arinO of a bell crank lever pivoted on a bracket mounted on the plate A". The lever arm 0 passes through a slot A in this plate. 'lwo bars Q lie along outside the ke rods I1 so that they are positioned beneati lugs H formed in the key rods so that on the depression of a key the lug .H will bear on one or other of the rods Q. These rods are carried at. their ends in frames Q pro vided with projecting arms Q, which pivot on a stay rod It. To a lever arm C," connected to the radius arm Q of the frame Q is a spring Q. The rods Q are this mounted so that. they can swingabout the stay rod it when a key is depressed the spring Q lifting the rods Q, back to their normal raised positions after a key has been depressed. One of the frames Q is connccted with the second arm of the bell crank lever which returnsthe selective strips the connection between the lever arm .0" and the frame Q, being such as to allow 'the necessary relative movement but insure the depression of the frame Q, imparting
